Rapid Development of a Commercial Process for Linrodostat, an Indoleamine 2,3-Dioxygenase (IDO) Inhibitor
摘要:
The process development and the kilogram-scale synthesis of linrodostat (BMS-986205, 1) are described. The synthesis features several highly efficient telescoped processes and the use of Evans auxiliary to install a methyl-bearing stereocenter. The target was prepared in 12 steps with 7 isolations in an overall yield of 31%.
